Comcast said it will also donate advertising time on its cable systems to those organizations to run public service announcements to help educate concerned citizens about how they can assist with flood relief efforts.

Its owned NBC and Telemundo stations also are implementing local phone banks and telethons to raise awareness of ways communities can help with the crisis in Houston, the company said.

Comcast, which had suspended operations in Houston as a safety precaution, has also opened 53,000 Xfinity WiFi hotspots in the Houston area to customers and non-customers to help residents and emergency workers there stay connected.
